Python，扭曲并使用cookielib向getPage添加cookie

Question

下面是我的代码，用于添加cookie以使用getPage获取页面。这也是我得到的错误信息。如何添加cookie？如果cookie为None，则代码正常工作。

 cj = cookielib.CookieJar()
 client.getPage(iUrl,headers,method='GET',cookies=cj).addCallback(self.processPage,iUrl).addErrback(self.printError,iUrl)

看起来您在cookie参数中传递了一个cookiejar。我找不到这种工作的参考资料。

我试着传递一个简单的dict，它起作用了。下面是完整的代码：

from twisted.web import client
import pprint

def processPage (page, url):
    print len(page), 'bytes received'
    print 'cookies: ', pprint.pformat(cj)

def printError(error, url):
    print 'ERROR: ', error.getErrorMessage()

def end(ignore):
    reactor.stop()

iUrl = 'http://twistedmatrix.com'

headers = []

cj = {}
client.getPage(iUrl,headers,method='GET',cookies=cj).addCallback(processPage,iUrl).addErrback(printError,iUrl).addBoth(end)


from twisted.internet import reactor
reactor.run()

下面是输出：

10660 bytes received
cookies: 
{'trac_form_token': '940bfe8055b63872303017ba',
 'trac_session': '5a3500ec1bc8efad40974a31'}
